Memory per contact
Each chat carries its own context — what they ordered, what you promised, how you usually talk. The draft picks up where you left off.

Your voice, learned
Write WhatsApp replies in your own voice — with AI that learns how you talk.
You can spot an AI reply from across the room. The over-polite "Thank you for reaching out!", the stiff sign-off, the tone that belongs to no one. Generic AI drafts fool no one — least of all the people who actually know you.
And on WhatsApp, that matters. WhatsApp is where you talk to regulars who have your number, suppliers you have known for years, friends who would notice instantly if you suddenly started writing like a help-desk macro. The register you use is part of the relationship. A reply that sounds wrong is worse than a slow one — it quietly tells the other person they are being handled by a machine.
ToTa-Ai is built around the opposite idea: the draft should sound like you wrote it, because it is learning from how you actually write. ToTa-Ai is an AI WhatsApp reply assistant for Android that reads your incoming message notifications, drafts a reply in your voice using per-conversation memory, and opens the right chat with that draft pre-filled. It never sends on its own.
Sounds like you
How ToTa-Ai writes in your register
ToTa-Ai pays attention to how you talk to each person — short and blunt with a supplier, warm and chatty with a regular — and shapes every draft to match. Same app, different voice, depending on who is on the other end.
Take a small shop running on WhatsApp. A customer asks about an order; the reply that lands is not a template — it is the kind of thing you would actually type, in the words you actually use. You glance at it, maybe fix one word, and send.
Behind that draft is per-conversation memory. This chat already knows the customer asked about a delivery, what you quoted, and how you usually wrap things up. So the next draft is not starting from a blank page — it is continuing a conversation it remembers.
Priya · regular customer
Bhaiya, the saree I ordered last week — has it shipped yet? Need it for Sunday 🙏
ToTa-Ai draft · high confidence
Hi Priya! Yes, it went out yesterday — should reach you by Friday, well before Sunday. I'll share the tracking link in a bit. 😊
Why memory matters
A reply in your voice needs context, not just style
Your register, learned
Formal with one person, casual with another. ToTa-Ai matches the tone you actually use with that contact — not a single house style.
A confidence read
Every draft comes with a high, medium or low confidence read, so you know when to skim and when to read closely before sending.
You stay in control
It drafts. You send.
ToTa-Ai is an assistant, not an autopilot. The send button is yours — by design, and by WhatsApp's rules.
- It opens the chat for you. ToTa-Ai resolves the contact and deep-links the draft straight into the right one-to-one WhatsApp thread, with the text pre-filled in the message box.
- You read, tweak, or rewrite. Change a word, add a line, or replace the whole thing. The draft is a starting point, never a finished decision.
- You always press send. ToTa-Ai never auto-sends. Nothing leaves your phone as a message until you tap send yourself.
- Read-only, revocable access. ToTa-Ai reads incoming notifications via Android notification access — explicit, revocable, and not an accessibility service. More in the how it works section.
Frequently asked questions
How does it learn my voice?
ToTa-Ai builds a per-conversation memory from how you actually write. Over the messages in a chat it picks up your register — how formal or casual you are, the phrases you reach for, how you greet and sign off — and uses that to shape each new draft so it reads like you, not a generic template.
Will replies actually sound like me?
That is the whole point. Drafts are written in the register you use with that specific contact — short and blunt with a supplier, warmer with a regular customer. Each draft also carries a confidence read (high, medium or low) so you know when to skim and when to read closely before sending.
Does it remember past conversations?
Yes. Per-conversation memory means each contact carries its own context — what they ordered, what you promised, how you usually talk to them — so the next draft already knows. That memory lives in a local database on your device.
Can I edit the draft before sending?
Always. ToTa-Ai opens the chat with the draft pre-filled in the message box. You can tweak a word, rewrite the whole thing, or send it as-is. ToTa-Ai never auto-sends — you always press send yourself.
Where is my conversation data stored?
Your conversation memory and contacts stay in a local database on your device. Message text is sent to a third-party AI provider only to generate a draft. See the privacy policy for the full detail, or reach us through support if you have questions.
